Patent GB-955794-A (GB)
Title: Glass coated glass fibres
Inventor: MORLEY JOHN GODFREY
IPC: C03C25/42
Filed: 1959-07-25
Abstract: A glass fibre of substantially constant cross-section is provided with a coating of glass having a lower viscosity factor fused into position so that at a predetermined temperature there is a gradual transistion from a solid phase at the centre of the glass to a liquid phase at the outer surface of the coating. Irregularities on the outer surface of the coating are thereby removed and a stronger fibre produced.  The coating is preferably applied e.g. as a sheet, while both glasses are in the solid phase. The coefficients of expansion of the glasses are chosen to be equal or such that the coating is placed under compressive stress on cooling.  A plurality of fibres may be joined to form a sheet. The inner glass composition given as example contains CaO 23.3; Al2O3 14.7 and SiO2 62, in weight percentages.

Patent GB-787927-A (GB)
Title: Recovery of gamma-butyrolactone
Filed: 1955-09-08
Abstract: Gamma butyrolactone is recovered from a mixture of the lactone containing also at least one glycol ester, derived from ethylene, propylene or 2 : 3-butylene glycol and a monocarboxylic acid having 1 to 4 carbon atoms, by solvent extraction with a liquid aliphatic or cycloaliphatic hydrocarbon.  Two phases result, one containing the bulk of the lactone and the other the solvent and most of the glycol esters.  The hydrocarbon solvent may be used with water whereby the lactone separates out as an aqueous solution.  If desired, the mixture may be extracted with the two solvents separately. Extraction may be batchwise or continuous, and co- or counter-currentwise, in one or more stages.  The crude butyrolactone mixture may be that obtained as a by-product in the partial oxidation of C3-5 aliphatic hydrocarbons to lower aliphatic acids, and that form of lactone should preferably not contain more than 2 per cent of acids.  In an example, a mixture of butyrolactone, acetic, propionic and butyric acids and minor amounts of glycol esters comprising mono- and di-esters of the above-mentioned glycols with C1-4 aliphatic acids and obtained by liquid phase oxidation of n-butane is fractionated to remove substantially all the acids and is then subjected to extraction with a solvent consisting of equal volumes of water and n-hexane, giving an aqueous phase, which on evaporation yields 98 per cent pure butyrolactone, and a hexane solution of the glycol esters from which the solvent is recovered for re-use. n-Pentane and n-heptane are other specified solvents.

Title: Curved moulds boats and like structures
IPC: B29C53/36
Filed: 1974-05-17
Abstract: 1473666 Boat construction R C MARCH 17 May 1974 [30 May 1973] 25792/73 Heading B7A [Also in Divisions B5 and B8] A boat hull, or a mould for a glass fibre or concrete boat, or a plug for such a mould, consists of elongate strips or plates joined edge-to-edge to give a shape of compound curvature, the stresses constraining the strips to lie in the desired shape are transmitted from strip-to-strip by edge flanges which are bolted, welded or glued together. The flanges may be joined by tongues and grooves which may be lubricated or provided with rollers to permit relative longitudinal sliding, to correct the shape of the body either on initial assembly or subsequently. During assembly, a first strip is attached to an edge frame 2, and then each subsequent strip is attached loosely to transverse frames 3 to get its longitudinal axis in the correct position. Finally the adjoining strips are fixed together, this process imparting twist and lateral bending and aligning the surfaces of the strips. The connections to the framework may then be removed. The strips may have surfaces which initially are plane or curved. The strips may be parallel sided, or barrelled as in Fig. 5. The strips may be made of metal or wood or plastics and the flanges may be of different material. For example a plywood strip may have extruded plastics flanges with connecting tongues and grooves incorporated in the extrusion. Alternatively the strips may be of foamed plastics or rubber or cellular metal, or may incorporate hollow plastics or solid rubber balls. The strips may be laminated, e.g. with a core of end grain balsa or expanded polystyrene. The strips may have longitudinal holes. The transverse stiffness may be increased by the use of transverse ribs or by means of glass each fibre laid transversely. Each strip preferably has a uniform longitudinal bending stiffness, i.e. it may be bent as easily about a horizontal longitudinal plane as about a vertical longitudinal plane, and a number of constructions are described in which the stiffness about a longitudinal plane normal to the surface of the strip is increased without increasing the torsional rigidity or transverse bending stiffness.

Title: Improvements in or relating to circuits for suppressing interference
IPC: H04N5/217
Filed: 1953-09-18
Abstract: 742,433. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 18, 1953 [Sept. 22, 1952], No. 25839/53. Class 40 (3). In an arrangement for generating television signals by scanning kinematographic film in which the film is intermittently imaged (during the blanking period) on the photo-cathode of an image-type camera tube the target of which is scanned during intervals when the image is obturated, undesired signals which occur in the tube output circuit during the blanking period (due to the high photo-electric current produced by the light image) are suppressed in a circuit which is rendered operative by the tube blanking pulses to effect such suppression. The suppression circuit comprises the arrangement shown in Fig. 1, the output signals a (Fig. 2) of the image-type tube which include undesired signal excursions occurring during the blanking periods t1-t2, t3-t4, being supplied thereto via terminals 8, 9. Pulses, such as b (Fig. 2), coincident with the tube blanking pulses are supplied via terminal 10 and are of such amplitude that the cathode of diode 3 is brought to the potential which the cathode of valve 1 assumes when the input signal is zero. Diode 3 is then non-conductive for the negative excursions of the undesired signals and the output signal (across terminals 11, 12) is as shown by the full line curve in c (Fig. 2). By supplying this latter signal with reversed phase, to a further circuit of the kind shown in Fig. 1, complete suppression of the undesired signal may be obtained. Specification 450,675 is referred to.

Title: Manufacture of hydrogen cyanide
Inventor: BELLRINGER FREDERICK JAMES
IPC: C01C3/02
Filed: 1951-11-06
Abstract: Hydrogen cyanide is manufactured by passing a gaseous mixture containing less than 5 litres (preferably less than 3 litres) of vaporized methanol or formaldehyde per 100 litres of said gas mixture and molar ratios of ammonia and of oxygen to the organic compound greater than 1 at 340-450 DEG  C. over a molybdenum oxide catalyst. Preferably the molar ratio of ammonia to the organic compound does not exceed 2 and the concentration of oxygen in the gaseous mixture does not exceed 20 per cent.  Inert gases such as nitrogen and steam may also be present and in the examples air is used as the source of oxygen.  The reactant gases may be pre-heated but in order to avoid ignition in the pre-heater some of the ammonia or organic starting materials may be added during or shortly before entry into the part of the reactor containing the catalyst.  The molybdenum oxide may be used alone or in conjunction with phosphoric acid, e.g. in the form of 1/8 inch pellets of a 20 per cent. phospho-molybdic acid-impregnated silica gel; alumina is also specified as a carrier. With low concentrations of methanol or formaldehyde, 1/10 -10 secs. are suitable contact times, and the latter may be arranged so that the organic compound is substantially used up.  A portion of the product may, however, be recirculated to obtain an increased proportion of hydrogen cyanide therein.  Cooling of the catalyst may be external, e.g. by a molten salt (in the case of a suitably narrow reactor) or interstage, using relatively shallow beds. Fluidized technique may also be employed.  Two or more reactors may be employed in series, the first employing a less active catalyst than subsequent ones.  The reaction products may be cooled, contacted with, e.g. a 15 per cent. w/w sulphuric acid solution to remove ammonia and scrubbed with water to obtain a solution from which concentrated hydrogen cyanide is obtained by distillation, or they may be contacted with alkali metal hydroxide or carbonate to give alkali metal cyanides. U.S.A. Specification 2,405,963 is referred to.
